Where are the spark plugs located on a chevy hhr motor?

[Rick H]

I want to put in some E3 spark plugs with Diamond FIRE technology into my Chevy hhr 2.4 liter. I don't know where they are located. Can someone tell me where and how to replace the spark plugs with what I have.

If you don't know where they are by popping the hood and simply taking a peek, then you CERTAINLY should not even consider doing the work yourself.
